NOTE Follow the instructions given below when designing, selecting and handling the product. The instructions on design and selection (installation, wiring, environment, adjustment, operation, maintenance, etc.) described below must also be followed. Product specifications The direct current power supply to combine should be UL approved as follows. Circuit (of Class2) which is of maximum 30 Vrms (42.4 V peak) or less, with UL1310 Class2 power supply unit or UL1585 Class2 transformer. The Pressure Sensor is a approved product only if it has a mark on the body. Use the specified voltage. Otherwise failure or malfunction can result. For the details of compressed air quality, refer to ISO 8573-1, 1.1.2 to 1.6.2: 2001. This can cause operating failure. If compressed air containing condensate is used, install an air dryer or drain catch before the filter and perform drainage regularly. If drainage is not performed regularly and condensate enters the secondary side, it can cause operating failure of pneumatic equipment. If regular drainage is difficult, the use of a filter with an auto drain is recommended. Applicable fluid is air, inert gases and incombustible gases. Do not use a fluid containing chemicals, synthetic oils including organic solvent, salt and corrosive gases. Otherwise, damage to the product and malfunction can result. Check the details of the specifications before using. Use the specified measurement flow rate and operating pressure. Otherwise it can cause damage to the Pressure Sensor or inability to measure correctly. Reserve a space for maintenance. Allow sufficient space for maintenance when designing the system. Product handling Installation Tighten to the specified tightening torque. If the tightening torque is exceeded the mounting screws and brackets may be broken. If the tightening torque is insufficient, the product can be displaced and loosen the mounting screws. Be sure to ground terminal FG when using a commercially available switch-mode power supply. Do not drop, hit or apply shock to the Pressure Sensor. Otherwise damage to the internal parts can result, causing malfunction. Do not pull the lead wire forcefully, not lift the product by pulling the lead wire. (Tensile force 50N or less) Hold the body when handling to avoid the damage of the Pressure Sensor lead to cause the failure and malfunction. For piping of the Pressure Sensor, hold the piping with a spanner on the metal part of the piping (Piping attachment). Holding other part with spanner leads to damage the Pressure Sensor. Eliminate any dust left in the piping by air blow before connecting the piping to the product. Otherwise it can cause damage or malfunction. Do not insert metal wires or other foreign matter into the pressure measurement port. It can damage the Pressure Sensor causing failure or malfunction. If the entering of foreign material to the fluid is possible, install and pipe the filter or the mist separator to the inlet to avoid failure and malfunction. -5-
Wiring Do not pull the lead wires. In particular, never lift a Pressure Sensor equipped with fitting and piping by holding the lead wires. Avoid repeatedly bending or stretching the lead wire, or placing heavy load on them. Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire. If the lead wire can move, fix it near the body of the product. The recommended bend radius of the lead wire is 6 times the outside diameter of the sheath, or 33 times the outside diameter of the insulation material, whichever is larger. Replace the damaged lead wire with a new one. Wire correctly. Incorrect wiring can break the Pressure Sensor. Do not perform wiring while the power is on. Otherwise damage to the internal parts can result, causing malfunction. Do not route wires and cables together with power or high voltage cables. Otherwise the product can malfunction due to interference of noise and surge voltage from power and high voltage cables to the signal line. Route the wires (piping) of the product separately from power or high voltage cables. Confirm proper insulation of wiring. Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess voltage or current being applied to the product, causing damage. Keep wiring as short as possible to prevent interference from electromagnetic noise and surge voltage. Do not use a cable longer than 10 m. Wire the DC(-) line(blue) as close as possible to the power supply. When analog output is used, install a noise filter (line noise filter, ferrite element, etc.) between the switch-mode power supply and this product. Environment Do not use the product in area that is exposed to corrosive gases, chemicals, sea water, water or steam. Otherwise failure or malfunction can result. Do not use in a place where the product could be splashed by oil or chemicals. If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even for a short time, it may be adversely affected (damage, malfunction, or hardening of the lead wires). Do not use in an area where surges are generated. If there is equipment which generates a large amount of surge (solenoid type lifter, high frequency induction furnace, motor, etc.) close to the Pressure Sensor, this may cause deterioration or breakage of the internal circuit of the Pressure Sensor. Avoid sources of surge generation and crossed lines. The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes in the system. Mount the product in a place that is not exposed to vibration or impact. Otherwise failure or malfunction can result. Prevent foreign matter such as remnant of wires from entering the Pressure Sensor. Take proper measures for the remnant not to enter the Pressure Sensor in order to prevent failure or malfunction. Do not use the product in an environment that is exposed to temperature cycle. Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product. Do not expose the product to direct sunlight. If using in a location directly exposed to sunlight, shade the product from the sunlight. Otherwise failure or malfunction can result. Keep within the specified fluid and ambient temperatures range. The fluid and ambient temperatures should be 0 to 50 C. Operation under low temperature leads to cause damage or operation failure due to frozen moist in the fluid or air. Protection against freezing is necessary. Air dryer is recommended for elimination of drain and water. Avoid sudden temperature change even within specified temperature. Do not operate close to a heat source, or in a location exposed to radiant heat. Otherwise malfunction can result. -6-
Adjustment and Operation Do not short-circuit the load. If using the product to detect very small pressure rates, warm up the product for 20 to 30 minutes first. There will be a drift on the analog output of approximate ±1% immediately after the power supply is turned on, within 10 minutes. Maintenance Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of air before performing maintenance. There is a risk of unexpected malfunction. Perform regular maintenance and inspections. There is a risk of unexpected malfunction. Perform drainage regularly. If condensate enters the secondary side, it can cause operating failure of pneumatic equipment. Do not use solvents such as benzene, thinner etc. to clean the Pressure Sensor. They could damage the surface of the body and erase the markings on the body. Use a soft cloth to remove stains. For heavy stains, use a cloth soaked with diluted neutral detergent and fully squeezed, then wipe up the stains again with a dry cloth. -7-
Model Indication and how to order Option Description Part number Remarks Connector for pressure sensor controller ZS-28-C 1 pc. Definition and terminology F O Terms F.S. (full span/full scale) Output impedance Meaning Abbreviation for full span and full scale; means the maximum fluctuation range of the Pressure switch rated value. For example, when the output voltage is 1 to 5[V], the F.S. will be 5-1 = 4[V]. (Reference: 1%F.S. = 4 0.01 = 0.04[V]) The resistance value of a component between the voltage outputting element and the output line at the output of the analog voltage output. It is indicated as a resistance value which is converted in accordance with the condition in which resistance is directly connected to the voltage output element. There may be an error in the output voltage depending on this output impedance and the input impedance of customers' equipment. (Example: If the Pressure switch with output impedance of 1kΩ is connected to the A/D converter to detect the analog output of 5 V, the detected voltage by the A/D converter becomes 5(V) 1(MΩ)/(1(kΩ) + 1(MΩ)) 4.995(V), and there is an error of approximate 0.005 V.) R Rated pressure range Repeatability Ripple The pressure range in which the Pressure switch satisfies the specifications. Values over this range can be set if they are within the set pressure range, but cannot assured the specifications to be satisfied. Reproducibility of the displayed value for pressure and ON-OFF output operating point when the pressure changes at a temperature of 25 o C. A type of chattering. -8-
